Speccaton of Letters Patent No. 35,279?, dated May 13, 1862.

To all whom 'it 'may concern:

Be it known that I, THOMAS SHAW, of the city and county of Philadelphiaand State of Pennsylvania, have invented a new and `Improved Mode ofFastening Armor- Plates; and I hereby' declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing and to the letters of reference marked thereon.y

My invention consists in the uniting of the plates firmly by means of afusible metal as hereafter described.

In order to enable others to practice my invention, I will proceed todescribe its construction and operation. e

On reference to the 'accompanying drawing which f'orms a part of thespecification, Figure l, represents a section of the wall of an ironclad boat in the course of construction. Fig. 2, a view of the same inthe direction of arrow, a, Fig. 3, a magnified portion of Fig. l, in thedirection of arrow f).

Similar letters refer to similar parts throughout the several views.

A, Fig. l, represents the first layer of plate, which is firmly securedto the side of the ship,by means of screws or bolts. y

B, is the second layer of plate, arranged so as to cover every joint 'ofthe rst layer of plate, as shown in Figs. l and 2, and is secured bymeans of the fusible metal as described hereafter.

Fig. 3, represents the plate in positionv ready to receive the fusiblemetal which is done this wise, after the plates, A, are secured to thesides of the ship, C, by means of screws, N. The plates B are put intheir proper position, leaving a space for the fusible metal to run andattach itself, allowing blocks of metal E to intervene for that purpose.The outside crevices are closed by means of wood or metal slat, Gr, toextend the whole length of the crevice, and is held lin position bymeans of T headed bolts. The

lower crevice intervening plate A and B is closed with fusible metal,I).

The surfaces of the plates A and B are intended to be covered with afusible metal previous to placing them in the position shown. The platesbeing now in position afore described, the molten metal is run in fromthe top sufficient to fill all the crevices, when it is allowed to coolthe slat Gr is removed and the bolt heads cut off.

F is an edge view of a sheet of metal which extends the whole length ofthe plate for the purpose of guiding the metal to the crevice awhilebeing poured in.

It is evident that there are many fusible TI-IOMAS SIIAW.
